Research in Motion (RIM), the makers of BlackBerrys, is having some problems. Their stock is down, the new line of products has been delayed for a year and there are rumors of corporate sharks looking to take a bite out of them.

In the view of most observers, the problem stems from too many choices. Since 2007, they have introduced 37 models including BlackBerrys that flip, slide, with touch screens, touch screens and keyboards, high and low end products. The product line is too complicated. In a recent NY Times article, a market research firm estimated that their market share slipped from almost half in 2009 to roughly 10 percent in the US.

Compare that to Apple’s iPhone. There have only been four since 2008 and all were the same but differed only in storage or capabilities from earlier models. Apple made it simple and less is more.
